Keeping the rainforest in tact would preserve $8.2 billion of annual revenue in the economy, but Brazil’s new president Jair Bolsonaro may be dazzled by short-term gains.

If you’re an environmentalist, the value of the Amazon rainforest—which amounts to half of the planet’s remaining tropical forest—is obvious. But for those more interested in the financial value of the biome, clear-cutting this magnificent ecosystem for farming, mining, and building infrastructure may seem like a more profitable endeavor than preservation.

“The forest should unambiguously be saved when measured in a purely economic sense,” reads the study, published in the peer-reviewed journal Nature earlier this month.

The $8.2 billion includes the economic benefit of sustainable industries that currently function in the rainforest, such as Brazil nut farming and rubber tree timber. But it also accounts for the economic benefits of the Amazon’s environmental influence, such as sequestering carbon dioxide and regulating the local weather.

Tearing down the forest would reduce rainfall so significantly that it would generate an $422 million annual loss to agriculture, defeating the benefits of having more land to farm on.

These numbers don’t come from some back-of-a-napkin calculation, but are the result of a rigorous economical study where the researchers analyzed dozens of contributing, and contradicting, factors to create a spatial map of the economic value throughout the Amazon. Even still, the researchers noted that these numbers only capture a fraction of “the immeasurable overall value of the Amazon forest.”
